sPEcIFIoATroNfoming part of ieders Patent No. 748,257, dated Deember 29, 1903- Application filed February 24, 1903l Serial No. 144.659. (No model.)

To all whom it may concern:

` Be it known that I, EDWARD BOEKENKAM?,

acitizen of the United States, residing' in the` city of St. Louis, in the State of Missouri, have invented certain new and usefulImprovements in Oil-Burners, of which the `following on line II II, Fig. I, with the oil-conductingA pipe leading to the burner shown in elevalion. Fig. III is an enlarged cross-section taken on line III III, Fig. II. Figs. IV and V are sections of modifications.

l designates an oil-conducting pipe through which oil flows from 'a fountain-reservoir.

2 is a feed-tube fitted to the pipe l and provided with an interior valve-seat 3, (see Fig.

11,) located intermediate of the ends of the tube.

4 designates a bowl `of ring shape surmounting the feed-tube 2, to which it is connected by a neck 5, that carries a pair of diverging tubular arms 6'.v The arms 6 lead to the bowl 4, with which they communicate through ducts 7 'attheir outer ends. In'the bottom of the bowl 4 is a ring 8, of asbestos or other absorbent material by, which oil is absorbed to be furnished for starting burner.

9 is a tubular post centrally positioned above the inner ends of thetubular arms and extending to a greater elevationv than the oillevel in the bowl 4.

10 designates a valve stem extending loosely through the post "9 an'dedownwardly ,therefrom into the feed-tube 2, in which it is screw,threaded,as seenv` at ll, Figs. Hand III. At the'lower end of the stem 10 is a couical'valve 12," that opposes the valve-seat 3 in the feed-tube 2. Extending longitudinally ot' the valve-stern 10 is a groove 13, that terminates atits lowerend within a chamber 1`14 above the valve-seat and terminates at `its upper end in communication with the diverging tubular arms 6.

l5 designates a key [itted to the upper end of the valve-stem l0 interior of the ring-bowl 4 and provided with a lever-arm 16, that eX- tends downwardly from the'key to a position beneath said bowl and then outwardly, as seen in Fig. II, where it'terminates in a handle 17 in a position convenient of access for operation to turn the key and rotate the valve-stem l0. By this construction the handle 17 of the key-lever arm is prevented from being heated during the use of the burner and is therefore always ina condition to per- `mit of its being grasped to actuate the valvestem without liability of the users hand being burned.

18'designates the supply-reservoir from 'which the oil to feed the burner-bowl 4 is delivered and in which' the oil' remains on a level with a corresponding point of elevation in the burner-bowl at its bottom, as seen in Fig. II. A

19 is a fountain-tank located in the supplyreservoir 18and having a leg 20, that extends downwardly beneath the bottom of the tank and is closed by acap 21, provided with an oil-exit orifice 22.

23 is a valve-rod the lowerend of which rests upon the bottom of the supply-tank l and which carries a valve 24, located above the orifice 22 in the cap 21. l

25 is a perforated hood in theleg 20, and 26 is a coil-spring surrounding the valve-rod 23 in said hood, by A"which the valve 24 is held seated in the orifice 22 previous to the placring of the fountain-tank 19 in the supplyreservoir 18.

In4 the practical use of my burner the oil to supply theburner is first placed in the fountain-tank 19, and theV tank is placed in the supply-tank 18, whereupon the valve 24 becomes unseated to permit the'flow of oil from `the fountain-tank into the supply-reservoir `and therefrom into the conducting-pipe l. The oil continues to flow from the fountaintank into the supply-reservoir until it reaches the level of the lower end of the leg 20, when the flow is stopped by reason of the leg being sealed by the oil, so that air cannot gain access to the fountain-tank to displace the oil therein. This level is maintained until it is lowered by the consumption of oil in the burner. The Valve 12 is then unseated by rocking the lever-arm 16 to rotate the screwthreaded stem, by which said valve is carried. On the unseating of said valve the oil iiows past the valve-seat 3 into the chamber 14 and gains access therein to the longitudinal groove 13 in the valve stem 10, through which it flows upwardly and enters the tubular arms 6. From these arms the oil passes to the ducts 7,'through which it flows to the bowl 4. By providing the tubular post 9, extending above the tubular arms 6 to a greater elevation than the level of the oil in the bowl 4, and consequently to a greater elevation than' the oil-level in the supplytank 18, I ,avoid the necessity of packingthe upper end of the post where the valve-stem 10 passes therethrough, inasmuch as the oil being always maintained at a lower level than the upper end of the post there is no liability of its egress through the post.

It is obvious that variations from the construction herein described maybe made without departing from my invention to obtain the same object sought to be accomplished in the burner-viz., that of conducting the oil longitudinally pastzthe valve-stem in the feedtube or burner.

In Figs. IV and V, I have shown modifications which are the equivalents of the construction shown in the other views, the modification shown in Fig. IV consisting of the introduction of a duet 2a, leading longitudinally through the feed-tube from the chamber 14pa at the lower end of the space occupied by the valve-stem 11a. In the modification shown in Fig. V a groove 2b extends from the chamber letb longitudinally through the feed-tube alongside of the valve-stem 11b.

I claim as my invention- The combination with a supply-reservoir, of a conducting-pipe leading from said reservoir, a feed-tube mounted on said conduct.- ing-pipe, tubular arms supported by said feedtube, a ring-shaped bu rner-bowl having communication with said tubular arms, a tubular post surmounting said arms and extending through the opening of said burner-bowl, spaced from the bowl, to an elevation above the normal level of oil in` said supply-reservoir, a valve-stem extend ing through said post into said Afeed-tube and adapted to be operated from above, and a valve lat the lower end of said valve-stem, substantially as set forth.

EDWARD BOEKENKAMP.
